Answer:

Cells with 46 chromosomes are called diploids cells because they have two sets each.

Explanation:

In the human being, somatic cells contain 46 chromosomes (23 pairs), representing the complete chromosomal charge, so they are called diploid cells.

Ploidy is based on the total number of chromosomes contained in a cell:

If the cell has the full charge of chromosomes —like somatic cells— is called diploid, and its formula is 2n.
Cells with half the chromosome charge are called haploid, their formula is n, and corresponds to sex cells or gametes.

Two haploid cells can unite during fertilization, to give rise to a diploid cell, the gamete, which represents the basis of sexual reproduction. In humans, Cells with 46 chromosomes are called diploids cells because they have two sets of chromosomes each.

Answer:

1. Explain why predators need to eat more than primary consumers.

Explanation:

Predators need to eat more than primary consumers because in the trophic pyramid, primary consumers are at the bottom which means they receive the most energy because they eat the plants. As the pyramid goes on upwards, energy is lost each time, so that means by the time it reaches the top of the pyramid their is only about 0.1% of the energy we started with when the primary consumers ate the producers. Meaning, the predators need to eat more than the primary consumers because although the predators eat more than the primary consumers, they still at the end of the day get the same amount of energy just one eats more than another.

Cell at metaphase of mitosis contains 20 sister chromatids, how many chromosomes will be present in a g1 cell? if a cell at meta

kumpel [21]

Answer:

The correct answer would be 10.

The cell cycle can be divided into four phases namely gap 1 (G₁) phase , synthesis (S) phase, gap 2 (G₂) phase, and mitosis (M) phase.

DNA (deoxyribonuceic acid) content is only replicated and doubled in the S phase. However, the chromosome number remains the same. It can be explained as the number of chromosomes remains the same (2n) but number of chromatids doubles (4n) after S phase.

The number of chromatids restores to 2n in daughter cells after completion of mitosis.

Hence, if number of chromatids in metaphase was 20 i.e. 4n then the number of chromosomes (2n) would be 10.

Hence, 10 chromosomes or 5 pairs of chromosome would be present in the cell during its G₁ phase.
